Hi,
In GITHUB is a pull request for a repair to Tuya Lights. It has been tested and works, but appears to have been missed by Franck Nijhof. Notifications are easy to miss for a busy person.
The request can be found at 2024.4 Tuya integration: lights white/color mode not updated. I believe the comments in GitHub accurately reflect the level of frustration that Tuya Light users are feeling.
